In an interview with ESPN, Lauren was asked how she has been in the months since his death

She said: 'I'm good. I feel strong. I feel happy. I am thankful he's at peace now. There has not been a moment, outside of the day it happened, where I felt like the carpet's been ripped out from underneath me.

'I've felt grace through this entire thing, and I have an awesome group of friends and family, and they will not let me fall. I've gained so much strength from my faith. I feel at peace right now.

'My girls give me strength and joy,' she added. 'They are doing so well. We comfortably talk about him. We can laugh and share memories and stories. I feel like they have this divine perspective.'

Dr. Lili-Naz Hazrati, a University of Toronto neuropathologist, examined the extreme sports legend's brain after he committed suicide in a van in February. She confirmed the 41-year-old suffered from the brain disease that has been diagnosed in a growing number of dead sports stars who got concussions throughout their careers

She said in the weeks before his tragic death, those close to him realized he wasn't being himself.

Some friends had also told him to watch the recently-released film Concussion to find out more.

Mirra took his own life within days of his 10th wedding anniversary, Daily Mail.com revealed in February.

An hour before dying from a self-inflicted gunshot wound the 41 year old posted a poignant photo and message about Lauren.

Under a photo of a smiling Lauren he wrote: 'My rock. Thank God!!'

The couple would have celebrated their 10th wedding anniversary on February 18th having married in 2006 in Napa, California.

Some shocked friends in his hometown of Greenville said the sportsman had shown no outward signs of being depressed.

The condition, called chronic traumatic encephalopathy, has been highlighted recently with many researchers looking into whether there is a connection between head injuries sustained in sports like ice hockey and football with issues like depression and dementia.

Mirra (pictured during a stunt in 2009) suffered a fractured skull when a car hit him at age 19, and tried boxing after his retirement from BMX in 2011. But he also endured countless concussions during his BMX career

Concussions are the most common brain injury in adults but especially among athletes - particularly with those involved in heavy contact sports.

Many athletes who sustain the injury have complained of various problems afterwards - including depression and anxiety.

In the latest study, published in Canadian Medical Association Journal, researchers looked at anonymous records of 235,110 patients with concussion over a 20-year period in Ontario using a health insurance database.

They compared those occurring on a weekend or weekday to distinguish between recreational and occupational injuries.

The average age of the patients was 41 years - about half of whom were men - and most lived in cities.

The majority had no prior suicide attempt, hospitalization or past psychiatric disorder.

During an average follow-up of 9.3 years there were 667 suicides, the researchers discovered.
